Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 97150761, filed Dec. 25, 2008. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of specification.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a photo-voltaic device and a display apparatus, and more particularly to a photo-voltaic cell device and a display panel.[0004]2. Description of Related Art[0005]In general, a photo-voltaic cell device is often made of silicon or group III-V semiconductors. After the photo-voltaic cell device is irradiated, free electron-hole pairs are generated in a material layer of the photo-voltaic cell device, and charges are separated because of electric field effects, so as to form a semiconductor device having a voltage difference caused by the electric field effects. Operation principles of the photo-voltaic cell dev...
